Microsoft has sent through word all-new free content is available today for Forza Motorsport 4 in the form of the 2013 SRT Viper Download Pack.

The 2013 SRT Viper Pack includes a drivable version of the SRT Viper with exterior and cockpit views, which highlight the car’s powerful on-track performance. Additionally, Turn 10 Studios worked with SRT to craft a brand new Autovista experience that highlights the car’s incredible features and details the model’s production history. As with the rest of the cars in Autovista for Forza Motorsport 4, fans will be able to explore and interact with the car using only their hands with Kinect or with their Xbox 360 controller.
